Smoke, shaded and tipped are all forms of silver-restriction colouration. A colour inhibitor gene restricts the colour to the hair tip while the shaft is either white/ivory (silver series) or golden (golden series).
Your health matters to you. You eat the right things. You work out regularly. You get the right amount of sleep. But when it comes to working out and sleeping, it can be hard to know if sleeping right after a workout provides benefits or hurts your health. If you have insomnia, a disorder that prevents you from achieving adequate sleep, working out before you go to bed might encourage sleepiness.
Exercise may also bolster sleep in other ways, because it reduces stress and tires you out. Early morning and afternoon exercise may also help reset the sleep wake cycle by raising body temperature slightly, then allowing it to drop and trigger sleepiness a few hours later. It can be especially helpful if you are able to exercise outdoors and let your body absorb natural sunlight during the daytime hours.
